I think the strategy for gpu nowdays is to hop on a new algo/coin, mine while profitable, then move on if the coin/algo goes asic. It takes at least a few months for asic makers to develop a miner for a new algo.
As long as new and profitable coins pump out. gpu miners are good. Just have to keep your eyes open and move your rigs aways from coins that have gone asic. The days of set it and forget it are gone after Eth went pos. For GPU miners there is onyl hope for future is Ergo,ironfish and a few kawpow coins thats all for now, xelis is amazing but how long, surely price will hold but hashrate will eat profits sooner or later. Hypra, ablian also require memory, maybe somewhat asic resistant. those coins are not doing too well atm though. Don't take my word. This well known crypto tuber red fox crypto was in 2017 bull run. Eth was a big thing in 2017 as it was in 2021. Watch his video about 5 things he wished he would have done differently. Not mining a bunch of alt coin was the first thing he mentioned.
If history repeats itself. Most alts will go nowhere.
